Abstract

PROBLEM TO BE SOLVED: To improve the constructing property by raising a riser above an invert having an outflow pipe, and displaying the height from the outflow pipe bottom part on the side surface of the riser. SOLUTION: This drainage basin is formed of an invert 1 having an outflow pipe 11 integrally formed thereon by use of, for example, hard vinyl chloride, a riser 2 provided on the upper part of the invert 1, a lid receiver 22 provided on the upper end opening of the riser 2, and a lid 23 installed on the lid receiver 22. A height scale 21 showing the height from the bottom of the outflow pipe 11 is provided on the outside surface of the riser 2. When an inflow pipe is connected to the riser 2, the construction is performed after the height is confirmed by the scale 21. According to this, since the inflow pipe can be connected to the riser without measuring the height from the bottom of the outflow pipe as in the past, the constructing property can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin in which a rising pipe is provided above an invert provided with an outflow pipe.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Utility Model Laid-Open Publication No. 1-79685, there is known a drainage basin in which a rising pipe is erected above an invert provided with an outflow pipe. In such drainage masu, when connecting the inflow pipe to the riser pipe, measure the height from the bottom of the outflow pipe provided on the invert at the connection point of the inflow pipe of the riser pipe,
After checking the height, the inflow pipe was connected.

[0003]

However, when the inflow pipe is connected to the rising pipe as in the conventional drainage basin, the height of the connection point of the inflow pipe of the rising pipe from the bottom of the outflow pipe must be increased. The measurement was complicated and time-consuming.

[0004] The present invention relates to the above conventional drainage basin,
The purpose of the present invention is to solve the above-described problems, and to connect the inflow pipe to the riser pipe when the inflow pipe is connected to the riser pipe. It is to provide a drainage basin without having to measure the height from the bottom of the pipe one by one.

[0005]

Means for Solving the Problems In order to achieve the above object, a drainage basin according to the present invention is a drainage basin in which a rising pipe is erected above an invert provided with an outflow pipe. The height from the bottom of the outflow pipe is indicated on the side of the pipe.

In the present invention, the material of the drainage basin is not particularly limited. For example, a hard vinyl chloride resin, a synthetic resin such as polyethylene, polypropylene and FRP, and an inorganic material such as concrete can be used.

In the present invention, as a means for displaying the height from the bottom of the outflow pipe on the side surface of the riser pipe, a character for indicating the height may be entered or a character may be engraved.

[Effect] In the drainage basin of the present invention, the height from the bottom of the outflow pipe is indicated on the side of the riser pipe. It is not necessary to measure the height of the connection point of the pipe from the bottom of the outflow pipe.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an example of the drainage basin of the present invention, FIG. 2 is a sectional view of the drainage basin of the present invention shown in FIG. 1, and FIG. 3 is a plan view of the drainage basin of the present invention shown in FIGS. . 1 to 3, reference numeral 1 denotes an invert made of a rigid polyvinyl chloride resin of the waste water of the present invention, 11 denotes an outflow pipe provided integrally with the invert 1, and 2 denotes a hard polyvinyl chloride resin provided above the invert 1. The rising pipe 2 is bonded to the invert 1.

Reference numeral 21 denotes a height display provided on the outer side surface of the riser pipe 2. The height display 21 indicates a position at a height H from the bottom 111 of the outflow pipe 11, and is shown in FIG. like,
Θ = 180 on the opposite side from the inflow pipe 11 on the outer surface of the riser pipe 2
It is displayed at a point within the range of degrees. The lower part of the height display 21 is displayed in increments of 5 cm, and the upper part is displayed in increments of 50 cm. In the illustrated embodiment, the bottom 111 of the outflow pipe 11 and the bottom 12 of the invert 1 have substantially the same height.

Reference numeral 22 denotes a hard vinyl chloride resin lid receiver provided at the upper end opening of the riser tube 2, and reference numeral 23 denotes a hard vinyl chloride resin lid provided on the lid receiver 22.

In the drainage basin according to the present invention shown in FIG. 1, the height indication 21 is provided on the outer surface of the riser pipe 2. Therefore, when an inflow pipe (not shown) is connected to the riser pipe 2, the riser pipe 21 is not connected to the riser pipe. There is no need to measure the height from the bottom 111 of the outflow pipe 11 at the point where the inflow pipe of the upper pipe 2 is connected, and the workability is excellent.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration of the present invention is not limited to the illustrated embodiment, and design changes within a scope not departing from the gist of the present invention. Are included in the present invention.

For example, instead of providing one inflow pipe 11 in the invert 1, a plurality of inflow pipes may be provided as in the drainage basin of the present invention shown in FIG.

[0015]

According to the drainage basin of the present invention, when connecting the inflow pipe to the riser pipe, it is not necessary to measure the height of the connection point of the inflow pipe in the riser pipe from the bottom of the outflow pipe. Excellent workability.
